Hl. Singh et Ak. Varshney, Synthesis and spectral studies of organotin(IV) complexes with bifunctional tetradentate Schiff bases, MAIN GR MET, 22(9), 1999, pp. 529-532
Coordination compounds formed by the interaction of metal ion with several
potentially tetradentate ligands [N,N'-bis(salicylaldehyde)2,6-diaminopy N,
N'-bis(2-hydroxy-1-naphthaldehyde)- 2,6-diaminiopyridine, N,N'-bis(benzoin)
2,6-diaminopyridine] have been prepared. Stoichiometries of the complexes h
ave been established by metal, carbon, hydrogen and nitrogen analysis and m
olecular weights, conductivity measurements, UV, IR and nuclear magnatic re
sonance (H-1, C-13 and Sn-119 NMR) spectral Studies. The tentative coordina
tion numbers and stereochemical environments around organotin(IV) are discu
ssed in each case.
